Exhaust wrap on Inlet pipe???

[Rusty]

Was having a look and a think at the old girl today and had a thought. Why not use exhaust wrap on the pipe that goes between the IC hose and TB hose to reduce heat soak from the turbo and exhaust that are next to it, bar a heat shield. I've included a piccy, although I'm sure everyone knows what I'm on about. Good excuse to show off the Samcos really .

Other options are to paint it any colour other than black to improve heat reflection inside the engine bay. I wonder why Audi painted it black in the first place??? maybe to follow the colourful interior scheme that I have inside the car with the highlight being white dials and carbon trim (don't get me wrong, I love it!). Or was it to dissapate heat from the inlet to the engine bay, thus renderring my above idea useless.

I know it wouldn't look too bling but to be hones I'm not bothered about 'detailing' the engine bay, just about improvements.

But it like this, Paul J covered that pipe in bacofoil and it worked a treat, after arriving at the RR, that pipe was stone cold. Must have done something. A few ppl have used various products on that pipe with good results.

I'm not sure that exhaust wrap would be the best thing to use. It's a made for a different temperature range. Bacofoil's tried and tested though! With a decent dyno plot to prove it!

Re Bacofoil:-

Of course! Better be careful with the insurance company though as such severe modification may cause issues!

On a more serious note... is it worth the hour or so effort?

[audiman]

Yep IMHO it worth doing

[S2 Ant]

im actually tempted to chuck some of that bacofoil in my engine bay as well now LOL, cheap and easy heat shield as im too lazy to make anything proper at the moment

[Billman]

Can someone please tell us what the Bacofoil is??? Is this Aluminium foil for the Oven??

[S2 Ant]

yes billman

[S2-racer]

are you guys serious, a cheap and easy modification for our cars????

surely you jest........ lol

[S2 Ant]

well it does look rather comical LOL but it does work!

Has Paul J got the metal inlet pipe underneath all that bacofoil ? The later plastic ones are better for heat dissipation, aren't they ?

Yeah it's metal and before the tin foil went on I painted with a £5 tin of the enamel heat shield paint stuff from halfords - which is in black for some reason. I tried painting it in the stuff before but with tin foil on the pipe is stone cold after a run. When the car's stood only then does it start to warm up.

Looks ***** but hey, it works! For the cost of a quid or so for the expensive tin foil (though any old crap will do I guess - it's all the same thing) and two jubilee clips/3 bolts to undo to get the pipe off I thik it's worth doing. Audi in their wisdom chose to suck cold air in, warm it up in the turbo, cool it down in the intercooler and warm it up through the intake pipe which gets red hot, so every little helps.

Also laid Bacofoil over the exhaust downpipe/turbo rather than wrapping it round.

If you're gonna put a cone in, at least give it a chance to do it's job! Give it some cold air and keep the hot air out, eh kids?

what about getting the pipe chrome plated, whats it made out of? i know there are some metals that you cant chrome. i was looking at the same pipe today thinking what i could do to it

[The Spanish]

Make it in 24K Gold. That will keep it cold
